WILLIAM M. R. MYERS, OF GREENSBURG, PENNSYLVANIA.

HORSESHOE.

To all whom it may concern:

Be it known that I, WILLIAM M. R. MYERS, a citizen of the United Statesof America, residing at Greensburg, in the county of Westmoreland andState of Pennsylvania, have invented certain new and use fulImprovements in Horseshoes, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to horse shoes and the object of the invention isto provide a horse shoe with detachable calks, whereby the calks can beremoved, sharpened and renewed when dull or broken. To this end, Iprovide a horse shoe with depending dovetailed tongues for holdingdetachable calks, the calks having dove-tailed grooves to receive thetongues, and cotter pins for looking the calks in engagement with saidtongues. This construction will be hereinafter described in detail andthen claimed.

Referring to the drawings :Figure 1 is a bottom plan of a horse shoeequipped with detachable calks, Fig. 2 is a side elevation of the same,Fig. 3 is a longitudinal sectional view of the toe calk, Fig. 4 is atransverse sectional view of one of the heels of the horse shoe, Fig. 5is a longitudinal sectional view of one of the heel calks, and Fig. 6 isa front elevation of the same.

Referring to the drawings in detail 1 denotes a horse shoe having thelower face of its toe provided with a depending transversely extendingdove -tailed tongue 2 formed intermediate its ends with an opening 3extending longitudinally with respect to the length of the shoe. Thelower face of the toe of the shoe being further provided in proximity toeach end of the tongue 2 with a depending lug 4, the forward face ofsaid lug extending at an inclination.

Coupled to the toe portion of the shoe through the medium of the tongue2 is a toe calk 5, the latter is provided with a dove-tailed groove 6for the reception of the tongue 2. The toe calk 5 has its forward edgeextending at an inclination and 1ts rear edge also extending at aninclination, but the inclination of the upper part of the rear edge ofthe calk is less than the lower part. The upper portion of the rear edgeof the call: is adapted to be engaged by the lugs 4. The rear edge ofthe calk 5 approximately centrally thereof is cut away to form a recess5 with which communicates a transversely-extend- Specification ofLetters Patent.

5 so that the bent ends 8 of the pin 8 will not project beyond the innerside of the calk 5 at the top thereof.

At the heel of the shoe depending longitudinally-extending dove-tailedtongues 9 are provided which are formed integral with the shoe and eachof which is provided with a transversely-extending opening 10. Each ofthe tongues 9 at its inner end is flanged as at 11 so as to limit themovement in'one direction of the heel calks.

The heel calks are indicated by the refer ence character 12 and each ofwhich is provided with a dove-tailed groove 13 for the reception of atongue 9. Each of the heel calks 12 in its inner side near the topthereof is formed with a cut-away portion 12 with which communicates atransversely-extending groove 14 in the top of each of the calks 12. Thegrooves 14 intersect the grooves 13 and register with the openings 10.Extending through the grooves 14, openings 10 and projecting into thecutaway portions 12 are cotter pins 15 which securely lock the calks 12to the 'shoe. The inner ends of the cotter pins are bent at right anglesas at 15 and extend in the cutaway portions 12 so that the said bentends of the cotter pins do not project beyond the inner faces of thecalks 12. The calks 12 are of the same width as the width of the end ofthe bars from which the shoe is constructed. The groove 13 in each ofthe heel calks 12 is closed at its outer end as at 16 which also acts asa means to limit the shifting movement of the calks 12 in one direction.

' From the foregoing arrangement and con struction of parts it isevident that the means employed for connecting the calks to, the shoeare protected from dirt and also flying stones and furthermore permit ofthe calks being quickly and easily removed when occasion so requires.

Having now described my invention what I claim as new, is

A horse-shoe comprising a transverselyextending dove -tailed tonguedepending from the toe portion thereof, a pair of lugs depending fromthe toe portion of the shoe and arranged in proximity to the ends of thetongue, the forward faces ofthehlugs being inclined, a calk providedwith a dovetailed groove in which is seated said tongue,

said calk having the rear face inclined-rand engaged by the inclinedfaces of the lugs, said calk having-its rear face providedwithavertically-disposed cut away portionintermediate the ends, saidtongue provided approximately centrally with a transverselyeXtendingopening, said ,calk having its upper face provided with a pair oftransversely-extending grooves which register with'said opening, one ofsaid grooves teror niinating in said cut away portion, and a pinextending through said grooves and WILLIAM MYERS.
